io - Read a file with line continuation characters in Python -

i'm looking nice pythonic way of reading file, , joining lines logical continuations of ones above, indicated line continuation character. e.g.

here normal line. line continues on  \ 2 lines. line continues over\ 3 \ lines. 

i've found 1 solution here: http://code.activestate.com/recipes/66064-reading-lines-with-continuation-characters, seems unwieldy. there nice solution daniel wang in comments using generator:

def loglines(rawdata):     lines = []     in rawdata.splitlines():         lines.append(i)         if not i.endswith("\\"):             yield "".join(lines)             lines = []     if len(lines)>0: yield "".join(lines) 

this works fine, provided can read whole file @ once. wondered if there built-in functions handle this, or whether has other suggestions.

with open("data.txt") fin:     line in fin:         line = line.rstrip('\n')         while line.endswith('\\'):             line = line[:-1] + next(fin).rstrip('\n')         print line         ... 

you can pull out generator if wish

def continuation_lines(fin):     line in fin:         line = line.rstrip('\n')         while line.endswith('\\'):             line = line[:-1] + next(fin).rstrip('\n')         yield line   open("long.txt") fin:     line in continuation_lines(fin):         ...
